fix(honcho): hide session banner when not explicitly configured

Add explicitly_configured field to HonchoClientConfig — set when the
config has a hosts.hermes block or explicit enabled flag, vs auto-enabled
from a stray HONCHO_API_KEY env var.  Banner only shows when this is true.

Based on #1960 by @erosika, reimplemented without duplicating config parsing.
